Dobrochinski, J.P.H. (author)Moored vessels are subject to wave forces and moments at different frequencies, which induce motions of the body and can be transferred to the mooring lines and fenders. Under extreme forcing and vessel motions, dangerous line breaking accidents can occur or the ship movements can be simply too large to continue the on/off-loading process,...master thesis 2014

Pol, J.C. (author)Design water levels are a basic concept in flood risk management practice. These water levels with a specified return period are used for the design of dikes and other flood protection measures along the river Meuse. Current practice is that these water levels are determined by hydrodynamic simulation of a standard design hydrograph at the...master thesis 2014

Al Saady, M. (author)In this study regular and irregular waves are simulated with a numerical model. The aim of this study is to perform a numerical investigation into the reflection and transmission of the different waves forcing in a porous breakwaters. There are different types of numerical models available for solving the behaviour of waves in coastal regions...master thesis 2014

Piccoli, C. (author)The assessment of port marine operations performance by means of simulation is treated in this master thesis project. The navigational services provided to vessel at the access channels, from their arrival to the berthing operations and from unberthing to vessels departure, are investigated and evaluated. In the case study, FlexSim is used as...master thesis 2014

Schoen, J.J. (author)Pipelines and cables on the sea bottom are usually protected by a cover of dumped rock. In case of maintenance or removal works, this cover has to be removed in order to expose the pipeline. This removal can be performed by means of a mass flow excavation process, created with a submerged jet flow. However, the exact erosion processes of a...master thesis 2014

Albers, T.S. (author)Floods cause, even in modern countries, a lot of victims and damage every year. Generally, countries invest in prevention and protection, yet, also emergency response measures could be a (last) option. Regarding the latter, a distinction is made between preventive emergency measures (e.g. sand bags to raise the crest level of a flood defence)...master thesis 2014

Tuinhof, T.J. (author)By its very nature dredging is an environmental impact, since dredging includes the excavation and/or relocation of sediment in a river, sea or estuary. One of the environmental impacts related to dredging is increased suspended sediment concentration (SSC) levels, forming plumes of sediment. These so called dredge plumes originate from spillage...master thesis 2014

Tian, K. (author)Introduction Typhoons and tsunamis are dangerous phenomena for our society and Japan has been exposed to both of these hazards. The risks of these hazards are getting bigger and bigger due to the growing population in the cities near these ‘dangerous’ coasts. This thesis focuses on the design of a storm surge barrier located in Tokyo bay to...master thesis 2014

Jiao, J. (author)The Dutch Wadden Sea is consisting of 7 tidal inlet systems separated by sandy barrier islands. The general morphodynamics and hydrodynamics of tidal inlets are relatively well understood, but the detailed interactions remain a prominent research interest. In this study, process-based computer models are employed as a tool to investigate the...master thesis 2014

Miranda, C.A. (author)The traditional Dutch way to deal with piping for river levees is the implementation of piping berms. The disadvantage of such a measure is the inland space required, especially in urban areas. Relief wells, on the other hand, require less or no inland space and therefore represent an attractive solution as mitigation measure against piping. The...master thesis 2014

Van Gils, A. (author)The coastal area is a dynamic environment that suffers from human interventions and climate change. This requires extensive research and monitoring of the coastal areas. Measurement systems play a key role in the monitoring. Current velocities are for example often measured to investigate local hydrodynamics. At the moment the ADCP is often used...master thesis 2014

Van Verseveld, H.C.W. (author)Hurricane Sandy (2012), which made landfall in New Jersey on October 29th, made devastating impact on the East Coast of the USA and struck major parts of New York City, including the economic centre of Manhattan. The total damage (in the USA and Caribbean) is in excess of 100 billion US$ with estimates ranging between 78 and 97 billion US$ for...master thesis 2014

Lavies, H.G. (author)The breakwaters of IJmuiden are of a unique design; a riprap core is covered with a thick impermeable asphalt slab. During construction and after completion, slope instability caused extensive damage. Placement of a concrete cube armour layer prevented further damage to the asphalt, but proved to be unstable and required a significant amount of...master thesis 2014

Kolijn, D.J. (author)The following research focuses on artificial underwater structures (a.k.a. artificial reefs) in a coral reef environment to mitigate the natural and anthropogenic pressures which reef systems are increasingly facing worldwide. The research question is stated as: “Establishing a method to determine if a multipurpose artificial underwater...master thesis 2014

Van der Zwaag, J. (author)The sediment composition of the sea bed is of relevance for various coastal properties such as bed forms, beach slopes and marine ecology. Furthermore it may significantly influence the morphological evolution of the coast. Knowledge about the processes forcing the spatial distribution of a certain grain size is therefore of great importance....master thesis 2014

Van Denderen, R.P. (author)Bed level changes during a flood can have large influence on the safety against flooding and the navigational function of a river. In 1997 measurements were carried out in the Waal during a flood. These measurements present an average decrease of the bed level in the order of 10 cm over a 10 km reach which is much larger than expected from the...master thesis 2014

Stam, G.N. (author)Recently, nourishments have been carried out on a large scale to counteract the on-going erosion along the Dutch Coast. The main advantage of these large beach extensions is that large stretches of coastline are protected for a long time scale (e.g. 20 years), which decreases the frequency of nourishing significantly. This is not only cost...master thesis 2014

De Vet, P.L.M. (author)Currently, morphodynamic models as XBeach show substantial overestimations of the erosion rates during breaching and overwash events at barrier islands. The presently used limitations on the Shields parameter and the sediment concentration do hinder erosion, but have undesirable side effects, e.g. the breaching process is suppressed. By...master thesis 2014

The Port of Rotterdam is searching for a strategy to close the timespan between commercial (functional)- and technical lifetime of for (customer-) infrastructure...master thesis 2014
